# Previewfold

> Drop in the PDF you sell and get a watermarked preview PDF, square thumbnails and pins in your shop's colours, made in your browser. Nothing is uploaded.

Previewfold is a browser only listing kit maker for sellers of printable resources (teacher resources, planners, party printables). The seller drops in the PDF they sell (up to 200 pages and 150 MB, read with pdf.js in a worker, never uploaded), chooses and orders up to 12 pages, and the page makes: a preview PDF of watermarked page pictures (watermark diagonal, centre or corner at 10 to 60 percent opacity, burned into the pixels so the text cannot be copied) at 72 to 150 dpi under a size target, lowering the dpi step by step and saying so; a cover thumbnail and up to 3 page thumbnails at 750 by 750, 1080 by 1080 and 1920 by 1080; and 3 pin layouts at 1000 by 1500 in 3 frame styles; all in the seller's saved brand kit (shop name, tagline, two colours, logo, title font). Text never overlaps page miniatures, miniatures keep their shape, every text colour is checked for 4.5 to 1 contrast with an automatic switch, and titles wrap to 3 lines then shrink, never clipped. Previewfold lays out your own pages. It does not write, draw or generate anything. Fixed rules, no accounts, nothing uploaded.

- [Guides](https://previewfold.com/guides/): Guides for printable sellers: what a preview shows, pins that read at thumbnail size, and one brand kit across listings.
- [What a good listing preview shows](https://previewfold.com/guides/what-a-preview-shows/): Which pages to put in a preview of a printable resource, how many, in what order, and how strong a watermark to use so buyers can judge it without taking it.
- [Pin layouts that read at thumbnail size](https://previewfold.com/guides/pins-that-read-small/): How a 1000 by 1500 pin reads when it is shown a few hundred pixels wide in a feed: title size, how many pages to show, contrast and what to leave out.
- [Keeping one brand kit across listings](https://previewfold.com/guides/one-brand-kit/): Choosing two colours, one title font, a logo and a watermark once, so every listing's thumbnails and pins look like the same shop.
